BACKGROUND Technical Field

The present disclosure relates generally to modular ceiling systems, forexample for suspended ceiling arrangements, wherein the modular ceilingsystems utilize modular elements that are suitable to being coupledtogether conveniently in various configurations, thereby making ceilingarrangements easier to install, to reconfigure, and also to maintain.Moreover, the present disclosure relates to methods of installing andreconfiguring aforesaid modular ceiling systems. Furthermore, thepresent disclosure relates to various types of modular elements that aresuitable to being employed in aforesaid modular ceiling systems. Theaforementioned suspended ceiling arrangements are conventionallyimplemented to utilize “T”-bars, with ceiling panels supported by the“T”-bars, wherein the “T”-bars are hung from corresponding structuralceilings. Moreover, the present disclosure also relates to methods formounting aforesaid modular elements onto the “T”-bars to support ceilingpanels and electronic devices provided therein.

Background

Contemporary buildings, for example houses or offices, are implementedto have a structural ceiling from which is supported a suspended ceilingarrangement. Typically, the suspended ceiling arrangement includes aplurality of ceiling tiles or panels hanging at a distance ofapproximately 30 to 50 centimeters below the structural ceiling. Thesuspended ceiling arrangement further includes a plurality of T-barsthat are configured to support the plurality of ceiling tiles or panelsin position; the plurality of T-bars are suspended from the structuralceiling, for example via an arrangement of wires. Specifically, such anarrangement of the plurality of T-bars provides cells to accommodate theplurality of ceiling tiles or panels therein. Additionally, aflush-finish of lower surfaces of the plurality of T-bars, and theplurality of ceiling tiles or panels are such that they appear as acontinuous mono-planar lower ceiling surface. Conventionally, suspendedceiling arrangements are found to be practical because wiring loomsrequired for lighting devices, optionally other devices such as fans,loudspeakers and such like, can be aesthetically hidden from view abovethe ceiling tiles or panels. However, depending upon a configuration ofsuspended ceiling arrangement employed, the aforementioned wiring loomcan become very scattered and chaotic, especially when it is modifiedafter installation by various people to retrofit additional functionaldevices at a height of the suspended ceilings.

A further issue that is encountered with contemporary suspending ceilingarrangements is that replacing the suspended ceiling arrangements, forexample when generally refurbishing a given building in which asuspended ceiling arrangement is installed, generates a lot of wastematerial that is potentially not straightforward to recycle or reuse;the waste material can be environmentally disadvantageous. Moreover,hazards of harmful dust falling over time from a structural ceiling ontoan upper surface of the suspended ceiling arrangement, the structuralceiling often having a rough bare concrete surface, can make replacingceiling arrangements hazardous to health for personnel handling agedsuspended ceiling arrangement elements. Concrete used in older buildingscan potentially sometimes include trace asbestos, radioactive hotparticles (for example in regions near nuclear power plants), as well asother types of irritant materials.

Lego® bricks are known to be a highly flexible and versatile children'stoy that allows for a high degree of reconfigurability when the Lego®bricks are reassembled together in a potentially a large number ofalternative configurations; Lega® bricks were first disclosed in agranted U.S. Pat. No. 3,005,282B (“Toy Building Brick”; inventor:Godtfred Kirk Christiansen) and their degree of reconfigurability wasrevolutionary for toys in the 1960's. By allegorical analogy with Lego®bricks, it is desirable to design a suspended ceiling arrangement thatis modular and suitable to being reconfigured and repurposed, withoutgenerating dangerous or problematic waste.

SUMMARY

The present disclosure seeks to provide improved modular ceiling systemsthat allow for the configuration of novel configurations with improvedappearance and performance as well as systems that easier initially toinstall, easier to reconfigure after initial installation (for exampleto achieve a modified functionality), and easier to recycle or reusewhen a building incorporating the modular ceiling system is beingdismantled or generally refurbished.

Novel supporting elements are used as separate or integrated componentsto enable multiple alternative configurations of modular ceiling systemscomprising functional modules, ceiling elements such as ceiling tiles,and T-Bar grids. Embodiments provide for configurations with multipleheight levels and orientations, particularly with light fixtures asfunctional modules.

Additionally,different versions of the invention are disclosed for mounting lightingassemblies in an interconnected line, array or pattern either onopposing sides of one or more T-bar elements or at or close to theintersection of T-bar main beam and cross beams. The novel lightingassemblies disclosed provide a variety of direct and indirect lightingfunctions and are typically based on LED light sources.

DETAILED DESCRIPTION

In the following detailed description, embodiments of the presentdisclosure will be described with reference to accompanyingillustrations, and ways in which the embodiments can be implemented.Although some modes of carrying out the present disclosure have beendisclosed, those skilled in the art would recognize that otherembodiments for carrying out or practicing the present disclosure arealso possible.

In overview, the present disclosure is concerned with modular ceilingsystems that include modular components that are employable to implementsuspended ceilings, also referred to herein as “suspended ceilingarrangements”. Contemporarily, suspended ceilings are popular becausethey avoid having to beautify aesthetics of structural ceilings ofbuildings, and also provides working spaces between upper surfaces ofthe suspended ceilings and structural ceilings in which functional itemscan be accommodated. The working spaces are suitable to being populatedby fixtures that provide enhanced functionality to given rooms. Themodular components of the modular ceiling systems of the presentdisclosure employ modular supporting elements. An example supportingelement pursuant to the present disclosure has a “U”-shaped portion thatfits over one or more “T” bars that are employed to implement a givensuspended ceiling, and includes at least one supporting portion that isprovided with an arrangement of one or more supporting features forsupporting at least one ceiling panel and at least one functional moduletherewith, for example light fixtures but not limited thereto. Moreover,such supporting elements can be fabricated from materials such asextruded Aluminum, molded plastics materials, sintered pressed powderedmetal and so forth. It will be appreciated that using metal forfabricating the supporting elements is advantageous for providing a highmechanical strength as well as enhancing heat conduction from the atleast one functional module mounted to the supporting elements; forexample, when the at least one functional module include electronicsmodules such as switch-mode power supplies, driver units, audio poweramplifiers, computing devices and the like, heat energy dissipatedtherefrom is beneficially conducted via the supporting elements toassociated “T”-bars for heatsinking purposes. It will be appreciatedthat the aforementioned at least one functional module potentiallyincludes at least one of: wiring looms, lighting modules, electronicassemblies such as driver units, sensors, sensor amplifiers, wirelessmultiplexers, computing devices and such like. Optionally, thesupporting elements are supported at junctions whereas a plurality of“T”-bars mutually meet, at a mid-point along a given “T”-bar, or along awidth of a given suspended ceiling panel. More optionally, thesupporting elements are two opposing supporting elements mounted on agiven “T”-bar at two respective longitudinal ends thereof. Beneficially,the at least one functional module, for power supply purposes and signalcoupling purposes, are connected in a “daisy-chain” manner across agiven suspended ceiling arrangement, thereby keeping an associatedwiring loom very simple with short wire links between mutually adjacentsupporting elements, and avoiding long and complex cable runs; suchavoidance of long cable runs potentially results in less weight needingto be supported by a given suspended ceiling, as well as potentiallyproviding a reduced risk of electrical fires due to electrical faults,and also potentially a reduced degree of electromagnetic interference.Optionally, the at least one functional module include therewith aspatially local data communication network that is either wire-based ornear-field wireless or a combination of both, thereby allowinguser-adjustable items such as light switch controls, temperaturecontrols, light intensity controls, light color controls, anti-sounddampening degree controls, ventilation effect controls to be implementedwirelessly, whereby these controls are beneficially installed at variousconvenient locations in a given room equipped with a module ceilingarrangement; such controls thus beneficially communicate wirelesslydirectly to their fixtures of the suspended ceiling, also referred as“suspended ceiling arrangement”, as aforementioned.

In such a manner, the modular ceiling system can be provided withmutually different color outputs, or with color outputs that can betemporally varied, for example to provide a dynamically-changing roomenvironment that mimics a natural outdoor environment, for example forreducing a feeling of claustrophobia or depression within the givenroom, for example for providing simulated white cloud effects on a lightblue background, wherein the white cloud effects slowly spatiallymigrate over a period of minutes within the suspended ceilingarrangement.

As mentioned earlier, it is beneficial that a power supply provisionfrom a given functional module of the suspended ceiling arrangement isbeneficially coupled in a “daisy-chain” manner to other functionalmodules that are adjacent to the given functional module. The functionalmodule can beneficially include a local data processing arrangementtherein, so that near-field wireless communication can be employed insuch a “daisy chain” manner; the modular ceiling system of the presentdisclosure thereby provides a spatially distributed and networked dataprocessing arrangement, for example so that sensor signal datacompression can occur locally to avoid large amounts of data, forexample video surveillance data, required to be communicated via themodular ceiling system. The functional module beneficially providesvarious power output options (e.g. DC output, AC output, overloadprotection, sensor inputs, control outputs, resonant inductive powercoupling connections, optical fiber data coupling connections forsupporting later retrofitted new types of functional module); thisflexibility allows various types of functional modules to be added laterthat have a wide range of power supply requirements. The spatiallydistributed and networked data processing arrangement can function asone or more nodes of a peer-to-peer data communication network, a localcomputing center, and such like. In order to make feasibleaforementioned functionalities of embodiments of the present disclosure,a key modular component used is the aforesaid supporting element thatfunctions as a “multifunctional mounting bracket”, as will be elucidatedin greater detail below.

The “multifunctional mounting bracket” is designed to mount onto one ormore “T”-bars of a suspended ceiling arrangement in an easy andcustomizable manner, allowing users to mount a wide variety offunctional modules onto the “multifunctional mounting bracket”. The“multifunctional mounting bracket” can be accommodated in a spatialvolume having a height extent of less than circa 52 mm (namely 2 inches(″)) within a suspended ceiling arrangement. As will be elucidated ingreater detail later, such a functional module potentially includes adriver unit that provides power to a ceiling region including aplurality of suspended ceiling panels. Beneficially, the“multifunctional mounting bracket” is designed to be easily understood,handled and installed by contractors and electricians (i.e. “tradespeople”) of modest skill and training; for example, installing the“multifunctional mounting bracket” involves:

-   (a) mounting at least one supporting element onto at least one    “T”-bar of a suspended ceiling arrangement;-   (b) installing at least one functional module onto the at least one    supporting element, wherein the at least one supporting element    provides mechanical support for the at least one functional module;-   (c) fitting at least one power module onto the at least one    supporting element; and-   (d) coupling electrically the at least one power module to the at    least one functional module.

Using such a method, an arrangement is implemented that is of arelatively small height profile (for example less than circa 50 cmheight), simple in form and aesthetically elegant.

In further overview, the aforementioned supporting elements of themodular ceiling system of the present disclosure can be, for example:

-   (i) used to install various functional modules including functional    device configurations in a given suspended ceiling arrangement;-   (ii) used to reconfigure a given ceiling arrangement to provide    various alternative functionalities thereto;-   (iii) relocated within the given suspended ceiling arrangement to    provide modified functionalities thereto; and-   (iv) re-used and recycled in a given suspended ceiling arrangement,    there assisting to maintain to given suspended ceiling arrangement    in an event of a malfunction arising therein.

The modular ceiling system thus employs an arrangement of supportingelements that can be used in a given suspended ceiling arrangement thatsupports a plurality of ceiling panels and/or various types offunctional modules. Furthermore, the supporting elements are capable ofsupporting one or more of the plurality of ceiling panels, for exampleat least one of:

-   (i) lower than the general ceiling plane;-   (ii) higher than the general ceiling plane;-   (iii) substantially at the general ceiling plane,-   (iv) at a tilted angle relative to the general ceiling plane.

The aforementioned functional modules are capable of coupling heatenergy generated therein via supporting elements to associated “T”-barsarrangement, whereat the heat energy can be effectively and safelydissipated; for such purpose, the supporting elements are beneficiallyfabricated from a metal, for example from extruded Aluminum or fromsintered metallic powder materials. Moreover, the supporting elementsare optionally mounted part-way, for example mid-way, along “T”-bars, orat junctions whereat a plurality of “T”-bars mutually couple or meet,wherein the supporting elements beneficially support one or morefixtures including various functional devices such as down-lights,sensors, ventilation fans, loudspeakers, anti-sound ports, wirelessrepeaters or hubs for “wifi”, and such like. Features and componentparts of the modular ceiling system will be described in greater detailbelow

Referring firstly to FIG. 1, there is provided an illustration of asuspended ceiling arrangement 100, implemented, at least in part, usinga modular ceiling system pursuant to the present disclosure. Thesuspended ceiling arrangement 100 includes a plurality of hanging wires104 coupled to a structural ceiling 106, “T”-bars 108 supported by thehanging wires 104, and a plurality of ceiling panels 110 arranged in anarray of cells 112 defined by the “T”-bars 108. In operation, a weightof the ceiling panels 110 is borne by the “T”-bars 108. Furthermore,lower horizontal downward-facing portions of the “T”-bars 108 define ageneral ceiling plane 114 for the plurality of ceiling panels 110.

The aforesaid modular ceiling system, used to implement at least a partof the suspended ceiling arrangement 100, utilizes at least onesupporting element 102 that, when in operation, supports given ceilingpanels 116A to 116C of the plurality of ceiling panels 110 in at leastone of:

-   (i) lower than the general ceiling plane 114;-   (ii) higher than the general ceiling plane 114;-   (iii) substantially at the general ceiling plane 114, and-   (iv) at a tilted angle relative to the general ceiling plane 114.

Furthermore, the aforesaid modular ceiling system includes at least onefunctional module 118, for example an electrically and/or electronicallyoperated ceiling device, that is supportable on the at least onesupporting element 102. Beneficially, the at least one supportingelement 102 is optionally fabricated from a material that ismechanically strong and is an effective heat-conductor, for example fromsintered compressed metal powder or from an extruded metal (for exampleextruded Aluminum or press-formed Aluminum, Copper or steel sheet),thereby enabling the functional module 118 to dissipate its internaloperating heat, if required, onto the “T”-bars 108 of the suspendedceiling arrangement 100.

Throughout the present disclosure, the term “suspended ceilingarrangement” refers to any ceiling consisting of a ceiling grid that issuspended or hung at a height below a structural ceiling of anarchitecture, such as a building. It will be appreciated that thestructural ceiling 106 is an overhead interior surface that defines aphysical upper limit of a given room. In an example, the structuralceiling 106 is at a height of 2.5 meters from a floor (not shown inFIG. 1) of the given room. In such an example, the height below thestructural ceiling 106 for suspending the suspended ceiling arrangement100 is 0.25 meters from the height of the structural ceiling 106, namely2.25 meters from a floor of the given room. Furthermore, the hangingwires 104 can optionally be hinged, hooked, tied, coupled, plasteredsecurely or fixed to the structural ceiling 106. In an exemplaryembodiment, the suspended ceiling arrangement 100 is supported by thehanging wires 104 at the height to provide a gap between the structuralceiling 106 and the suspended ceiling arrangement 100, wherein the gapprovides a space to accommodate the at least one functional module 118.

Optionally, the suspended ceiling arrangement 100 includes the “T”-bars108 disposed in a grid formation, for example as illustrated in FIG. 1;beneficially, the “T”-bars 108 are implemented as elongate metal bars,for example implemented as mild-steel bars formed from mild-steel stripto provide, when viewed in cross-section, a lower planar portion and acentral portion that is disposed centrally and orthogonally to the lowerplanar portion; in use, the lower planar portion is horizontallyoriented, and the central portion is vertically oriented and above thelower planar portion. It will be appreciated that a weight of the one ormore supporting elements 102 is supportable at various locations alongthe central portion of the “T”-bars 108. Ends of the “T”-bars 108 meetat intersecting junctions of the grid formation, as described in theforegoing. As aforementioned, the “T”-bars 108 are suitable to have oneor more supporting elements 102 mounted thereonto at the intersectingjunctions of the “T”-bars 108 that are capable of bearing considerableweight, or at positions along the “T”-bars 108 that are spatially remotefrom the aforesaid intersecting junctions.

FIG. 23 is a perspective view of an exemplary suspended ceilingarrangement 2300, beneficially including the supporting elements 1702 ofFIG. 17 and a supporting element 2302. The supporting elements 1702 and2302 support a ceiling panel 2304, wherein the ceiling panel 2304 issupported above a ceiling plane 2306. Furthermore, the supportingelement 2302 supports a ceiling panel 2308 thereon, such as, on alateral supporting element 2310. As shown, the ceiling panel 2308 issupported below the ceiling plane 2306. Furthermore, the supportingelements 1702 support a functional module such as ceiling device 2312,(wherein the ceiling device 2312 is at least one of: electricallyoperated, electronically operated) wherein the ceiling device 2312 canbe implemented as a sensor. Moreover, the supporting element 2302further comprises a power module 2314, for providing electrical power tothe ceiling device 2312, for example implemented as a light source 2316.

Optionally, at least one of:

-   (i) an external surface of at least one linear supporting element:-   (ii) at least one of the plurality of lateral supporting elements of    the supporting element 1702; and-   (iii) the supporting element 2302,    comprises at least one of: a colored surface, a textured surface,    and a reflective surface. For example, an external surface of the    light guide supporting element 1706 comprises a blue-colored surface    and an external surface of the linear supporting element 1708    comprises an angularly-textured surface (such as, a surface that is    configured to reflect light only when the light is incident thereon    at specific angles). It will be appreciated that such reflection and    scattering of the incident of light in different colors and along    different paths, enables to provide an aesthetically appealing    ambiance within a given room in which the suspended ceiling    arrangement 2300 is installed; for example, at least one of optical    diffraction gratings and prismatic optical components are included    in the suspended ceiling arrangement 2300 so that perceived colors    of the ceiling panels to a given used change as the given user moves    about within a room equipped with the suspended ceiling arrangement    2300. Furthermore, such a reflection of the incident light that is    potentially emitted from natural sources, reduces a requirement for    providing artificial light within the room, thereby, allowing to    reduce energy consumption (and consequently, cost thereof) for    lighting purposes within the room; such a manner of operation is    potentially capable of reducing Carbon Dioxide emissions associated    with electrical power generation, thereby assisting to reduce    impacts of potential anthropogenic climate change (“Green channel”).    Optionally, the textured surface comprises at least one of: a    light-diffusing surface, a specular surface, an angularly-textured    surface.

Optionally, at least one of a linear supporting element of thesupporting element 1702 and the supporting element 2302 is fabricatedusing a first type of material, and at least one of the plurality oflateral supporting elements of the supporting element 1702 and thesupporting element 2302 is fabricated using a second type of material,wherein the first and second materials are optionally mutuallydissimilar. For example, the linear supporting element 1708 isfabricated using extruded Aluminum and the light guide supportingelement 1706 is fabricated using recycled plastics material.Furthermore, for example, the linear supporting element 2318 isfabricated using stainless steel and the lateral supporting element 2310is fabricated using Carbon fiber material, for example Carbon fibercomposite. In such an example, fabricating the at least one linearsupporting element and the plurality of lateral supporting elementsusing different elements, enables to provide different structuralproperties thereto, while controlling a manufacturing cost associatedwith fabricating the suspended ceiling arrangement 2300. For example,fabricating the lateral supporting element 2310 using Carbon fiberenables to provide increased tensile strength thereto while reducing amass thereof, thereby, allowing lateral supporting element 2310 tosupport the ceiling panel 2308 thereon and reduce at least one of: anoverall mass of the suspended ceiling arrangement 2300, an overall massof the supporting element 2302. Reducing a mass of the suspended ceilingarrangement 2300 is beneficial in Earth-quake prone regions of theWorld, for providing protection against Earth-quake induced ceilingcollapse. Furthermore, fabricating the light guide supporting element1706 using recycled plastics material enables to provide increasedsafety associated with use of an electrically insulating material forhousing a device therein, wherein the device is at least one ofelectrically operated, electronically operated. Alternatively, the lightguide supporting element 1706 is fabricated using steel, therebyallowing absorption of heat generated by the ceiling devices 1710 and2312 therein, wherein the ceiling devices 1710 and 2312 are at least oneof: electrically operated, electronically operated. Consequently,fabricating at least one of the at least one linear supporting elementand the plurality of lateral supporting elements using differentmaterials, enables to provide different physical properties (such as,electrical insulation, heat absorption, sound absorption and so forth),as well as different visual appearances thereto, thereby, furtherenabling to improve aesthetic appearance of the suspended ceilingarrangement 2300. More optionally, the first type of material and thesecond type of material comprises one of: Aluminum, extruded Aluminum,steel, metal, metal alloy, ceramic, composite, plastic. For example, thefirst type of material is a metal such as Copper, a metal alloy such asstainless steel or a ceramic such as polyether ether ketone (PEEK) andthe second type of material is a composite such as Carbon fiber or aplastics material such as recycled polycarbonate or polyvinyl chloride(PVC). Optionally, the first type of material is same as the second typeof material. For example, the first type of material and the second typeof material are stainless steel.

Referring next to FIGS. 24A to 24C, it will be appreciated that thesupporting element of the modular ceiling system can be implemented inmany different manners; for example there is shown a supporting elementindicated generally by 2400 that includes a U-shaped portion 2410 thatmounts, when in use, over the central vertical portion of a “T”-bar 2420as well as two supporting portions 2430 that receive fittings,terminating in elongate distal flanges 2440 that are capable, forexample, of supporting ceiling panels of a suspended ceilingarrangement. Two such supporting elements, as shown in FIG. 24A, can be,for example, disposed at a junction whereat a plurality of “T”-barsmutually couple or meet. Such a junction is potentially capable ofbearing a considerable weight of functional fixtures.

FIGS. 25A to 25C provide illustrations of supporting elements 2502, 2504and 2506 for a suspended ceiling arrangement, in accordance with anembodiment of the present disclosure. As shown, each of the supportingelements 2502, 2504, 2506 includes a mounting portion that, when inoperation, is detachably mountable on a plurality of “T”-bars, namelytwo or more “T”-bars; the U-shaped portion fits over an upper edge of avertical central portion of the “T”-bars. Specifically, the U-shapedportion of each of the supporting elements 2502, 2504, 2506, when inoperation, encloses an intersection formed by at least two or more“T”-bars. For example, as shown in FIG. 25A, the supporting element 2502has a mounting portion 2512 that, when in operation, encloses anintersection formed by four “T”-bars. Similarly, as shown in FIG. 25B,the supporting element 2504 has a mounting portion 2514 that, when inoperation, encloses an intersection formed by two “T”-bars. Furthermore,as shown in FIG. 25C, the supporting element 2506 has a mounting portion2516, that, when in operation, encloses an intersection formed by three“T”-bars. The supporting elements 2502, 2504 and 2506 can be used inconjunction with any one or more of the suspended ceiling arrangementsof FIGS. 11 to 23, and are able to bear a significant weight of afixture by distributing the weight of the fixture along an extensiveportion of the “T”-bars. The weight can, for example, correspond tovarious fixtures, for example light fittings and/or other devices asillustrated in FIGS. 27A, 27D, 27E, 27F, 27G and 27H; the other devicesoptionally include sensors, ventilation fans, anti-sound injectionports, loudspeakers, water sprinklers (for fire safety) and such like.In such an example, ceiling panels of the suspended ceiling arrangementscan be modified by cutting at least one of edge and corner openingstherein to provide space for the fixtures, for example down-lights,thereby enabling, for example, the down-lights to be retrofittedtogether with their respective supporting elements 2502, 2504 and 2506to a pre-existing suspended ceiling. Alternatively, such selectivecutting of at least one of edge and corner openings of ceiling panelscan also be done for a new suspended ceiling installation, for which theone or more the supporting elements 2502, 2504 and 2506 are to beemployed. Thus, use of the supporting elements 2502, 2504 and 2506 canbe invoked independently, alternatively concurrently with, selectivemounting of ceiling panels above, below or at a tilted angle relative togeneral ceiling plane, as aforementioned.

Referring next to FIG. 26, there is provided an illustration of asupporting element 2600 for a suspended ceiling arrangement, inaccordance with an embodiment of the present disclosure. As shown, thesupporting element 2600 includes a support bracket 2602 that is integralto a “U”-shaped portion 2604, that, when in use, fits over a verticalcentral portion of a “T”-bar. The supporting element 2600, when inoperation, is capable of supporting various fixture modules, associatedwith a typical suspended ceiling arrangement, for example a lightsource, a sensor, one or more wires, a charger, a power source, such asa battery, a driver, a ventilation fan, a water sprinkler system, aloudspeaker and so forth. On account of the support bracket 2602 beingdisposed adjacent to the “U”-shaped portion 2604, the support bracket2602 is able to bear a considerable weight while also proving highlyeffect heat-shunting to the “T”-bar on which the supporting element 2600is mounted when in use.

Moreover, the supporting element 2600 has a coupling channel 2630adjacent to the “U”-shaped portion 2604 for receiving a driver module orsimilar. The driver module is beneficially installed by sliding into thecoupling channel 2630 and being retained by way of small retainingflanges provided along the coupling channel 2630; alternatively, thedriver module is retained in the coupling channel 2630 by way of afastening arrangement such as screws, clips, adhesives, releasableretaining blocks and so forth.

Optionally, the coupling channel 2630 accommodates in use a plurality ofdriver modules, for example a DC driver unit, a sensor interfacing unithaving one or more sensor inputs, a resonant inductive power couplingunit, a data relay unit providing the ceiling arrangement with apeer-to-peer wireless communication network, and so forth. Optionally,the plurality of driver module, or single driver module if employed, arecoupled in a “daisy chain” arrangement so that long cable runs within agap formed between a structural ceiling and an upper surface of panelsof the suspended ceiling arrangement are avoided, allowing a singleinput power feed to the suspended ceiling arrangement to be employed.Such a “daisy chain” configuration can be achieved using short“pig-tail” wire connections for coupling a given driver module to itsnearest neighboring driver module in the suspended ceiling arrangement,wherein the “pig-tail” wire connections have plugs for connecting todriver modules together; by “short” is meant having a length in a rangeof 20 cm to 3 meters (metres), more optionally in a range of 0.5 meters(metres) to 2.5 meters (metres). In situations where the suspendedceiling arrangement is prone to flooding or becoming water-logged, such“pig-tail” wire connections have plugs that transfer their power viaresonant inductive power transfer via coupling ferromagnetic coresincluded at the plugs. Such resonant inductive power transfer iscomprehensively described in a published PCT applicationWO2013/091875A2; “Inductive Power Coupling Systems for Roadways”, andprovides a technically enabling basis for a person of ordinary technicalskill to implement embodiments of the present disclosure, implementedwirelessly. The driver modules, in such a case, employ plugs havesplit-C ferromagnetic cores therein, wherein the cores are provided withcorresponding windings, and power is transferred when the split-C coresare abutted together to form a complete magnetic circuit implemented viathe cores. Use of resonant inductive coupling avoids a risk ofelectrocution to personnel, and allows fixtures to be replaced“on-the-fly” without need to decouple electrical power from thesuspended ceiling arrangement during maintenance.
